• Shares withheld/disposed: 2,283 at $487.76 each — ~$1,113,556 total
• Transaction code: F — "Payment of exercise price or tax liability" (shares surrendered/withheld to cover tax)

Context
A code F withholding is a routine corporate action used to satisfy taxes due from option exercises or restricted stock vesting; it does not necessarily indicate a decision to sell shares on the open market or signal a view on the company. Retail investors should treat tax-withholding dispositions as administrative, and consult the full Form 4 (or subsequent amendments) for complete ownership details.
